Senior Unity Developer

Senior Unity Developer TapNation is a mobile game publisher specializing in hyper-casual and hybrid-casual games, with over one billion cumulative downloads. The role Ship games — quickly and well. You are the studio's technical multiplier: a senior developer who, augmented by coding agents, delivers what a small team used to deliver, without compromising on architecture or game feel. Responsibilities Develop prototypes and complete games in Unity (C#), from concept to live, on cycles of days to weeks Make AI-assisted development (Claude Code, Cursor, Copilot, Unity MCP) your default way of working, while remaining fully accountable for architecture, code quality, and maintainability Build the studio's tooling: asset generation pipelines, automated QA agents, CI/CD, and editor tools that accelerate the whole team Integrate and master the full SDK ecosystem (ads, analytics, MMP, IAP: GameAnalytics, Adjust, Adapty, ad mediation platforms) Optimize rigorously: memory, framerate, build size, and load times across a highly heterogeneous Android and iOS device base Challenge Product Managers on feasibility and propose technical solutions that expand design possibilities Requirements 5+ years of Unity/C# development in mobile F2P, with shipped games that are publicly available — you should be prepared to walk through your titles and your precise role on each Demonstrable technical excellence : clean architecture under speed constraints, advanced profiling (Memory Profiler, Frame Debugger), and deep familiarity with mobile performance pitfalls Advanced practice of AI-assisted development : you have restructured your workflow around these tools and have a clear, tested understanding of what can be delegated to an agent and what cannot A strong sense of game feel : you can explain what makes a game satisfying to play, and you know how to reproduce it Proven velocity : you have prototyped in days rather than months, and you can demonstrate it Full autonomy: you identify what needs to be done without waiting to be told Fluent English required If your experience with AI tools is limited to code completion, or if you have not shipped games end to end, this position is unlikely to be the right fit. Nice to have Internal tools or agents you built that are used by people other than yourself Monetization expertise (ad waterfalls, placements, mediation, IAP) Shaders, VFX, or advanced game feel skills Open-source contributions or side projects that demonstrate your level Département Product Locations PARIS OFFICE, Europe Remote status Hybrid
